What are the symptoms of a damaged fuel pump?

[EvelynLynn]

Signs of a faulty fuel pump include: 1. Weak acceleration with noticeable jerking during sudden acceleration. 2. Difficulty starting the engine, requiring prolonged key turning. 3. Unusual noises, such as a buzzing sound while driving. 4. Illumination of the engine warning light. 5. Engine vibration. Below is relevant information: 1. Poor fuel quality: When fuel quality is substandard, the fuel tank may contain various impurities or foreign particles. Although the fuel pump has a filter screen to strain the gasoline, it only blocks larger particles while smaller ones are sucked into the fuel pump motor, causing damage over time. 2. Delayed refueling: The habit of waiting until the fuel warning light comes on before refueling can lead to the fuel pump operating at a low fuel level, resulting in insufficient cooling and lubrication. This can cause the electric pump motor to overheat and stop working. 3. Fuel filter: If the fuel filter is not replaced regularly, severe clogging in the fuel supply system can occur, making it difficult for the fuel pump to deliver fuel. Prolonged operation under high load can lead to fuel pump damage.
